concertina226 (2447056) writes Scientists at China's Southwest University in Chongqing are working on a new type of camera that takes Big Brother to a whole new level – the camera is meant to detect highly stressed individuals so that police can catch them before they commit a crime. The camera makes use of hyperspectral imaging, i.e. a 'stress sensor' that measures the amount of oxygen in blood across visible areas of the body, such as the face. Chinese authorities are deeply concerned about the recent spate of deadly attacks occurring in public places, such as the mass stabbing attack by eight knife-wielding extremists in the city of Kunming, Yunnan in March, which left 29 civilians dead and over 140 others injured.

>Please officer I'm 20 minutes late for work not a terrorist!>Sorry, we need to verify your identity and make you 20 minutes later>Portable scanner: warning stress level increasing, violence imminent"Sorry boss, I got shot on my way to work this morning"

Or just clenching your butthole. That's the supposed trick against lie detectors, anyway:)
I somehow think it would have the opposite effect against this terror cam, but I'm not about to go on a killing spree, so I can't test it.

Don't think that would work, as lie detectors are based off of heart rate and skin salinity (I think), whereas this camera operates by recording a persons "aura," for lack of a more scientific term.

Point being, a true sociopath, such as a religious fanatic, isn't going to show stress the way the authorities would expect them to. All this camera is going to catch are the people with high blood pressure, and those of us who get nervous around cops.

> whereas this camera operates by recording a persons "aura," for lack of a more scientific term.

Aura? Seriously? No. Not even close. It works by looking for small fluxuations in skin color that result from changes in blood flow. This same technique has been investigated as a tool for medical use as well.

I am pretty sure that clenching your anal sphincter, or any other muscle in your body, will result in changes in blood flow. Actually given how poor most people's motor control actually is, it will proba

They are simply using UV or IR imaging (most likely IR, as increased oxygenation in the surface blood will alter the temperature of the skin) and since IR falls outside our typical range of visible light, calling it Hyperspectral imaging is quite correct.

You may be mistaking Spectrum and Spectre here and ending up with a ghost who's ingested too much sugar.

I wasn't aware that testing people for the ability to calm down was so important. Guess fuck anyone with an anxiety disorder. Only a couple of them anyway, and as long as they can be quiet about it no harm no foul right? So what if they experience a little personal hell for....

> The I important thing to remember is 99% of the time it's going to be a false positive

99% is one time in a 100 is not a false positive? I have trouble believin

People on the way to the dentist, or a job interview, or even a first date might get called in. At the same time Muslims take great pains to brutalise and desensitise [dailymail.co.uk] their kids so they will be less likely to show stress.

There you go again complaining about Muslims. You really are a tiny-minded, scared xenophobe. It sounds like you and your ilk would set these sensors off in a heart-beat, as you seem utterly scared of Muslims, of whom you seem to know next to nothing. You are pathetic.

Israel army (on phone to Gaza officials): We're going to be bombing this building, so make sure you get all the children, women, and others out.Hamas terrorist: HA! Children! Stay where you are! You are safe here from the Jewish infidels! Don't move!---- bombs drop ----Hamas terrorist (to foreign media): That accursed Israeli army! They bombed children! How could they!

What other military actively warns the enemy ahead of time that they're going to be bombing a specific target? It's Hamas that makes s

This scale bad to good defines most Muslims (80+%).1. Willing to kill and die to further Islam.2. Not willing die but willing to kill.3. Not wanting to do the killing themselves. but supportive of it.4. Not sure if killing for Islam is good or bad5. Believes killing for Islam is wrong to an extent, but not going to risk doing anything to stop it.6. Believes killing for Islam is wrong but won't risk openly opposing killing for Islam.

Unfortunately, There are almost no Muslims who are closer to the last step

Someone always has to put in a defensive "But America does it too" whenever we discuss negative characteristics of China or its government. I notice the urge generally isn't there when we discuss the foibles of Europe and most other parts of the world. Even commentary on the various ongoing spying scandals tend to remember that the US isn't the only offender.

: The fetishization of China by certain weirdos as a place of 'economic liberty' (lol), or at least something worth kowtowing to, just in case.: The fear of appearing racist. This is due to a confusion of China (the culture) with Chinese (the race). In a bit of amusing irony, this confusion comes partly from the intense xenophobia of the Chinese culture itself. Here's a hint: corruption and brutality are not strongly heritable traits.: False liberal

As stupid as I think this is, its a valid point. In fact, I highly doubt any terrorist foot soldiers are sociopaths.

What sociopath would risk his own life for a cause? That isn't a very sociopath thing to do. The place for the sociopath is planning the attack and finding the ideological folks to carry it out.

The actual low level terrorists are more likely disaffected and pissed. Fathers and sons who see themselves as getting revenge for a killed family member, for example....you know.... the kind of people

If stress is probable cause for warrantless attention, Americans have no rights at all, because stress--not liberty--is the cornerstone of our lives.

Whoa, back the FBI surveillance van up there cowboy. The article has nothing to do with the US. This is about China. Sure, if this technology takes off, there is a good chance that the TSA and NSA would be next in line. However, it is way too early to start decrying the loss of American civil liberties over this story.

"One of the most important advances in casino technology comes from facial recognition systems, where guests entering the gambling area are photographed and their visages are compared with an ever-growing database of known cheaters and suspicious people."

'Terrorists' quickly discover that a few milligrams of clonazepam right before the big martyrdom operation is way less haram than getting shitfaced and at least as effective at masking anxiety. In other news, state security services are stretched thin in their new battle against 'cosmetics', a class of nefarious concealment powders and pigments specifically designed to mask the user's true facial state. On a happier note, authorities report that perps with anxiety disorders are much easier to interrogate than the other kind and credit a 58% increase in the number and detail of mostly-voluntary confessions to a new focus on these low resistance criminals...

This also won't work against the "terrorist" Buddhist monks who have decades of training in maintaining a perfectly zen state of calmness even in extreme situations... however their shaven heads and robes might be a dead give away.

"The Chinese foreign ministry has accused the Dalai Lama of "terrorism in disguise" for supporting Tibetans who have set themselves on fire in protest against Beijing's rule." - http://www.theguardian.com/wor... [theguardian.com]

You could just change the government there and allow people more freedoms, including religion. Being fascist dickwads certainly isn't helping things. I'm not an advocate for religious practice however peoples' beliefs can force them to do something awful just to draw attention to their plight. Instead of stabbing people randomly, people being repressed in China could be like Shen Yun [goo.gl] and put on a show about it. No? Well okay carry on then creating something that'll put more people in jail or bring bac

Well sadly FDs also get help from those Democracy loving nations around the world so it's not just fascists helping fascists out there. Lots of companies for example are helping the repression in Bahrain but nobody really says much because "there one of the good Arab nations"

Yeah and they do it because we let them do it. Frankly I have more hope of turning around the situation of over-surveillance all in the name of stopping crime/terrorism. Unfortunately in China, the people don't have much of a choice in the matter at all. It would be an opportunity to take the lead in China for human rights by getting rid of this system of repressing society and maybe the world would follow that lead.

I hope you know Falun Gong is a cult devoted to a single man, and deprives its followers of every single freedom. The western depiction is like the western depiction of Tibetan Budhism as saintly when reality of history shows it as brutal when in power. Think dismemberment for petty crimes. Falun Gong is worse.

In the attempt of "detecting stress", they would probably be "causing stress" because there is now always someone watching you (not that you might be committing anything, just the lack of comfort due to people always watching you). So pretty much getting rid of people who has the potential of camera shyness

What is needed is more knife-control laws, or, as they're known in this country, "knife-safety" laws. It is self-evident that if the government were to take away everyone's knives, these kinds of incidents would cease.

Civil liberties don't routinely extend to manufacturing devices specifically designed to kill other people and then handing them out to anyone who wants them without any questions being asked. Even devices with other uses but that are demonstrably dangerous to other people get limits placed on them to ensure people are competent (e.g., cars) before letting them loose in public spaces. There is no "right to drive", for example. You have to show that you have a *very*basic* level of competence.

There is an easy test. Just play "Stuck In The Middle With You." If they pull out a razor and start dancing, they are obviously a Psychopath and you shoot the bastard before he takes off someone's ear.

inmate: So youre the new guy. I got 15 years for murder. what did you do?new guy: suspicion of terrorism at a train station. The cops said their new camera detected my enormous amount of stress.inmate: thats gutsy. So, did ya pull it off? the terror attack?new guy: if by terror attack you mean a taco bell breakfast, then yeah. Im sure theres a plumber and a janitor that are pretty terrorized by me.

For a split second I was thinking this tech would be useful in schools to spot people about to go on a murder spree, but then I remembered that a school would have an ungodly false positive rate. It would be interesting to see if it would be of much use to find people who are being regularly bullied, spot those who are under constant stress in school and reach out to them to provide assistance, long before they go on a murder spree.
